Combination smoke alarm and wireless location device

Abstract

The present disclosure relates to a device and method for determining and automatically transmitting a geographic location of a wireless smoke alarm during a potential fire emergency. The wireless smoke alarm includes a smoke alarm interfaced with a wireless transceiver, which operates over an existing wireless telecommunications network. The wireless transceiver can be a cellular processor with an integrated memory for storing emergency identification data. In one mode of operation, upon sensing the presence of smoke, the wireless transceiver automatically transmits stored emergency identification data signals to a dispatch center.

 a transmitter in communication with the integrated memory and the alarm control circuit, the transmitter configured to automatically and contemporaneously transmit at least a geographic location of the wireless smoke alarm to a dispatch center when the alarm control circuit is activated; and 
 an alarm disabling mechanism to at least temporarily disable the alarm control circuit, wherein the alarm disabling mechanism is configured to be inoperative beyond a number of uses. 
 
   
   
     9. A wireless smoke alarm to transmit data to a dispatch center, the alarm comprising:
 an integrated memory having an enhanced wireless 911 service; 
 a sensor configured to generate a signal when an amount of smoke is detected; 
 an alarm control circuit in communication with the sensor and configured to receive the signal from the sensor; 
 a transmitter in communication with the integrated memory and the alarm control circuit, the transmitter configured to automatically and contemporaneously transmit at least a geographic location of the wireless smoke alarm to a dispatch center when the alarm control circuit is activated; and 
 a time delay control circuit to temporarily delay a transmission of the signal to the transmitter. 
 
   
   
     10. The wireless smoke alarm of  claim 9  wherein the geographic location of the wireless smoke alarm is determined by a global positioning system in communication with the integrated memory. 
   
   
     11. The wireless smoke alarm of  claim 9  wherein the geographic location of the wireless smoke alarm is stored in the integrated memory. 
   
   
     12. The wireless smoke alarm of  claim 9  wherein the transmitter coupled with the integrated memory comprises a cellular telephone. 
   
   
     13. The wireless smoke alarm of  claim 9 , further comprising:
 a housing encompassing the integrated memory, the smoke sensor, the alarm control circuit, and the transmitter. 
 
   
   
     14. The wireless smoke alarm of  claim 9 , further comprising:
